Abstract
A cutting device and corresponding method for cutting a relatively rigid material, such as for example paper, cardboard, plastic material, composite or other. The cutting device includes a first cutting disc sharpened along its peripheral edge and rotating around a first axis of rotation. A second cutting disc, also sharpened along its peripheral edge and rotating around a first axis of rotation (X3), is disposed in front of the first cutting disc with respect to the material and is co-planar with the first cutting disc (14).
Claims6
A cutting device for cutting a relatively rigid material (11), comprising:
- a first cutting disc sharpened along its peripheral edge and rotating around a first axis of rotation (X2);
- and
- at least a second cutting disc (19) sharpened along its peripheral edge (21) and rotating around a second axis of rotation (X3),
- wherein said second cutting disc (19) is disposed upstream of said first cutting disc (14) with respect to a direction of feed into said cutting device and is co-planar with said first cutting disc (14),
- wherein said first cutting disc (14) and said second cutting disc (19) are on a same side and mobile individually or together, with respect to a support plane (12) on which a workpiece to be cut is to be rested, so that a distance between the peripheral edge (16, 21) of each of said cutting discs (14, 19) is selectively adjustable with respect to said support plane (12), and
- wherein said first cutting disc (14) and said second cutting disc (19) are rotatably mounted on a first (15) and respectively second support slider (20), said first and said second support sliders (15, 20) being mounted on a fixed structure (17) and mobile with respect thereto in a direction perpendicular to the support plane (12) to adjust a distance between the first and the second cutting discs (14, 19) and the support plane (12).
A cutting method for cutting a relatively rigid material (11), comprising:
- a first cutting step, in which said material (11) is cut by a first cutting disc (14) having a sharpened peripheral edge (16) and rotating around a first axis of rotation (X2);
- and
- at least a second cutting step, in which said material (11) is cut on a same side as in said first cutting step, before said first cutting step takes place, by a second cutting disc (19) having a sharpened peripheral edge (21), rotating around a second axis of rotation (X3) and disposed in front of, and co-planar with, said first cutting disc (14),
- wherein a distance between the peripheral edges (16, 21) of the first and the second cutting discs (14, 19) is adjusted with respect to a support plane (12), on which said material (11) to be cut is rested, by moving said first cutting disc (14) and said second cutting disc (19) individually or together, with respect to said support plane (12), and
- wherein said first cutting disc (14) and said second cutting disc (19) are rotatably mounted on a first (15) and respectively second support slider (20), said first and said second support sliders (15, 20) being mounted on a fixed structure (17) and mobile with respect thereto in a direction perpendicular to the support plane (12) to adjust a distance between the first and the second cutting discs (14, 19) and the support plane (12).
